The Research And Implementation Of Mall Websites Based On Feature Variability Model

With the gradual expansion of software applications,the number of software products has shown an exponential growth trend,and software reuse has become particularly important.Software product lines have become a research hotspot because of the large-scale software reuse.The key issue of the software product line is how to manage the variability of the public feature set,and realize the reuse of the software core assets based on variability management.The variability modeling is a key technology of variability management and can provide new system development with reuse software requirements specification and guide the production of core assets in the domain design phase.The feature variability modeling method is widely used in software product lines.However,the poor operability of methods and the inability to realize the traceability of domain characteristics to the consistency of core assets have been a problem to be solved.This paper improves the requirements for variability modeling and the two-phase design modeling method.In the demand phase,the probability of the feature exists in the sample system is calculated by designing the table,the variable point is accurately determined,the ambiguity of the base is reduced,the variable point representation is simplified,and the operability of the feature model method is improved;during the design phase The introduction of layered ideas on feature partitions corresponds to the layering of the architecture,the concept of variable components is introduced,the concept of responsibility and the mapping algorithm are given,the many-to-many relationship between decoupled features and variable components,the use of variable components The interface can realize variability at the design stage and realize the traceability of the characteristics of the domain to the consistency of the core assets.In this paper,the improved feature modeling method is applied to the development of the mall website,which effectively improves the quality of the mall website and shortens the time for new products to go online.Finally,the improved feature modeling method is evaluated from the effectiveness and performance.This article makes a certain supplement to the theoretical research of the product line feature model,and has certain guiding significance for the product line development of the mall website.
